Comprehensive arrangement method of bauxite raw storage pile

Abstract

The invention discloses a comprehensive arrangement method of a bauxite raw storage pile, which comprises an ore unloading system (1); the ore unloading system (1) and an ore crushing system (2) are connected with each other by belt conveying, and are arranged at one side of an outdoor ore storage yard (4); an ore homogenizing silo (5) is arranged at the other side of the outdoor ore storage yard (4); the rear end of the ore crushing system (2) is connected with a first transfer station (31); the rear end of the outdoor ore storage yard (4) is connected with a second transfer station (32); the rear end of the ore homogenizing silo (5) is connected with a third transfer station (33); and the three transfer stations are connected together by belt conveying. The comprehensive arrangement method is compact in arrangement, and the land area, the road paving area and the pipe network laying length are saved by more than 10% compared with separated arrangement, so that the investment of project capital construction is greatly reduced.

Description

technical field [0001] The invention relates to a method for arranging bauxite. Background technique [0002] In the production of alumina, bauxite raw materials are transported from the mine to the factory through transportation equipment, and are generally stacked in the raw material yard, and the massive ore is crushed to reach the particle size allowed by the grinding production facility to meet the production requirements The ore should also be stacked in the homogenization warehouse for mixing and homogenization, so that the ore-containing grade fluctuation of the ore for a certain period of time is within a certain allowable range, so as to ensure the normal production. [0003] In the usual raw material storage yard layout, the ore unloading system, ore crushing system, ore open-air storage yard and ore homogenization warehouse are scattered and arranged in different locations in the factory area, and then connected in turn by conveyor belts and transfer stations. Th...

AI Technical Summary

Problems solved by technology

[0003] In the usual raw material storage yard layout, the ore unloading system, ore crushing system, ore open-air storage yard and ore homogenization warehouse are scattered and arranged in different locations in the factory area, and then connected in turn by conveyor belts and transfer stations. This layout method As a result, the land area of ​​the factory area increases, the road paving area and pipeline laying length increase accordingly, and the factory infrastructure investment and production and operation costs increase
